A simple question... How do I hook up a monitor to my projector using a VGA connector when the input jack is already being used by a HD sat. box? I noticed a similar connector next to it but it's labeled as an out-put (monitor loop through). Can someone please explain the correct way to hook up both a HD satellite box and a monitor using the same type of connector? The reason I'm using a VGA cable for the monitor is because my computer is located approx. 20 feet from my projector and I just happened to have a 25 foot cable. Any help would be appreciated!
